Within this material world He's also there. In some of the universes. There are innumerable universes, I have already explained. Somewhere He is there. So a devotee just after giving this body, giving up this body, immediately he is transferred to that universe where Kṛṣṇa is there. And when he's trained up, then he is, again, he's transferred to the Goloka Vṛndāvana, the spiritual sky. These are the description of Sanātana Gosvāmī in Bṛhad-bhāgavatāmṛta, how a living entity...
So in this way we are changing our body but because we are minute particle of Kṛṣṇa.... We have got qualities of Kṛṣṇa not cent percent. Seventy-eight percent. When they are perfect, so minute quantity, then we can also become a little more advanced than at the present moment. But not like Kṛṣṇa. Kṛṣṇa is cent percent perfect. We can become minutely perfect, seventy-eight percent. These are all analyzed by the Gosvāmīs. So in the present stage, our conditioned stage, there is no comparison with Kṛṣṇa, what to speak of becoming Kṛṣṇa. The rascal foolish persons, they claim that they have become Kṛṣṇa. It is not possible. This is the defect, that we forget. They ask so many the incarnation of God, about his past life. They cannot speak.
So this is the qualification of God. He knows past, present and future. And those who are false God, they cannot say. That is not possible. This is the test. They are claiming, falsely claiming. But God means, He knows. His body does not change. Past.... He knows past, present, future means His body does not change.
Why He does not change? That is described in the śāstra. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Vigrahaḥ means body, form. This transcendental form is made of sac-cid-ānanda. Sac-cid-ānanda. Sat means eternal, eternity. Oṁ tat sat. So sat, cit. Cit means full of knowledge. Full of knowledge here, tāny ahaṁ veda sarvāṇi. This is called cit. He knows everything, past, present and future. Sat, cit, and ānanda. You see Kṛṣṇa's form here, ānanda. He's enjoying. This is real Kṛṣṇa's form. He is always enjoying. Ānandamayo 'bhyāsāt in the Vedānta-sūtra it is said. He's ānandamaya. Kṛṣṇa, real form...
The Kṛṣṇa's form in the battlefield of Kurukṣetra, that is not Kṛṣṇa's real form. That is Kṛṣṇa's Vāsudeva form. Kṛṣṇa expands Vāsudeva, Saṅkarṣaṇa, Aniruddha, in that say. So this is a great science, Kṛṣṇa science. If you are interested, there are books you can study and you can understand what is Kṛṣṇa. Janma karma (ca) me divyaṁ yo jānāti tattvataḥ (BG 4.9). So everyone should try to understand Kṛṣṇa in truth.
